Hi Roger,

Thanks for writing in with your idea! We are always working to add features that improve our site, and we love getting input from our community.

While we wish we could implement all of our users' requests, we need to make difficult decisions about which features and requests are aligned with our goals at the time.

As our needs and resources change, it’s possible that we may be able to revisit this issue at a later date, but I can’t guarantee that we’ll be able to do so, or provide a timeline for when that might happen.

Thanks again for your interest in improving Khan Academy :)

All the best,
